Subject: [dpdk-stable] [PATCH v2 1/4] regex/mlx5: fix size of setup constants
Date: Thu, 1 Jul 2021 09:39:13 +0300
Message-ID: <20210701063916.2016763-1-michaelba@nvidia.com> (raw)
In-Reply-To: <20210601071122.1612432-1-michaelba@nvidia.com>

The constant representing the size of the metadata is defined as a
unsigned int variable with 32-bit.
Similarly the constant representing the maximal output is also defined
as a unsigned int variable with 32-bit.

There is potentially overflowing expression when those constants are
evaluated using 32-bit arithmetic, and then used in a context that
expects an expression of type size_t that might be 64 bit.

Change the size of the above constants to size_t.

Fixes: 30d604bb1504 ("regex/mlx5: fix type of setup constants")

v2: use size_t and uintptr_t instead of uint64_t.
